The poem describes the life of a tiger trapped in a zoo cage, contrasting it with how the tiger should be living freely in the jungle. The tiger paces around its small cage with quiet rage, when it should be lurking and hunting prey under the cover of shadows. It ignores visitors to the zoo, when it should be terrorizing villages at the edge of the jungle. At night it hears patrolling cars and stares at the stars, confined while remembering its natural habitat. The poet's message is that wild animals belong in their natural environments rather than in cages.
